• Exchange and superposition of distributed GIS
  Data via Internet and other services (e.g. LBS),
  independent of the raised domain-specific data,
  geographical data, software technologies and data
  provider

The integration of relevant GIS data in the IFC
data model has been going to be modelled and
developed since October 2003 in Norway (s. IFG).
The research group SIG 3D of "Geodaten-Infrastrukt
ur NRW (GDI NRW)" has been working since 2001 on
data exchange models for a 3D GIS
